Description

Technical Field

[0002] Backfill mining is a mining method that uses solid materials (such as mine tailings, coal gangue, etc.) to fill the voids in the mine. The principle of this method is to fill the mined-out area with ore waste or other solid materials while mining, forming a stable geological system. This can ensure that as much ore as possible is extracted while avoiding damage to the surrounding environment and facilities caused by surface subsidence of the mine. Backfill mining plays an important role in mine engineering. It can not only improve the mining efficiency, increase the utilization rate of mineral resources, but also reduce the occurrence of disasters such as mine surface subsidence and earthquakes. Currently, backfill mining has been widely applied in various types of mine mining, such as metal mines, coal mines, salt mines, etc.

[0031] The water supply mechanism 2 includes a water supply pipe 21 and a water pump 22. One end of the water supply pipe 21 communicates with the fixed cylinder 11, and the other end of the water supply pipe 21 communicates with the outlet of the water pump 22;

[0032] One end of the grip rod 3 is fixed to the fixed cylinder 11 and is located on the other side of the fixed cylinder 11.

[0033] During use, when a pipe blockage occurs, first determine the location where the blockage occurs, then turn off the pumping device, and then disassemble the blocked pipe section 4 from the pipe sections 4 at both ends. Then, hold the grip rod 3 by hand, insert the drill bit 13 into the blocked pipe section 4 and make contact with the blockage body 5. After that, connect the inlet of the water pump 22 to a water source, and then pump water through the water supply pipe 21 into the fixed cylinder 11 by the water pump 22. When the water passes through the vortex fan blade 12, it will drive the vortex fan blade 12 to rotate, and the vortex fan blade 12 drives the drill bit 13 to rotate, so as to drill a hole in the blockage body 5. At the same time, after the water is discharged from the fixed cylinder 11, it will flow to the position of the blockage body 5. On the one hand, it can cool the drill bit 13, and on the other hand, it can also carry away the drilled slurry. Continuously move the position of the drill bit 13, so as to completely drill out the blockage body 5. After the dredging is completed, reconnect the dredged pipe section 4 to its original position.

[0034] The technical solution provided by the present utility model passes the drill bit 13 into the blocked pipe section 4 through the grip rod 3, passes water into the fixed cylinder 11 through the water pump 22 and drives the vortex fan blade 12 therein to rotate, and the vortex fan blade 12 drives the drill bit 13 to rotate, so as to drill the blockage body 5 in the pipe section 4. The water discharged from the fixed cylinder 11 can cool the drill bit 13 and carry away the drilled slurry. With this device, the pipeline dredging effect can be improved, and at the same time, the pipeline will not be broken.

[0035] It should be noted that this device is applicable to the dredging of pipelines formed by sequentially connecting multiple pipe sections 4, and is not applicable to the dredging of relatively long continuous pipelines. For example Figure 5 As shown, in order to facilitate the determination of the blocked pipe section 4, two adjacent pipe sections are connected by a connector 6. Both ends of the connector 6 are connected to the two pipe sections 4 through flanges. An observation port 61 is opened on the side wall of the connector 6, and an observation valve 62 is provided on the observation port 61. During normal transportation, the observation valve 62 is in a closed state. When a pipe blockage occurs, open each observation valve 62 in sequence to determine the blocked pipe section 4.

During use, water enters the cover body 14 after passing through the scroll fan blade 12, then enters the rotating sleeve 15, and then sprays out from the water outlet hole 151. Since the water outlet direction of the water outlet hole 151 faces one side of the drill bit 13, the sprayed water flow can be made to shoot towards the blockage body 5.

[0038] In one embodiment, please refer to Figure 3 and Figure 4 , the drilling mechanism 1 further includes a bearing 17, the inner ring of the bearing 17 is fixedly sleeved on the rotating sleeve 15, and the outer ring of the bearing 17 is fixedly connected to the cover body 14.
